Greg Egan – Anatomy of a Hatchet Job:
A few reviewers complained that they had trouble keeping straight the physical meanings of the Splinterites’ directions. This leaves me wondering if they’ve really never encountered a book before that benefits from being read with a pad of paper and a pen beside it, or whether they’re just so hung up on the idea that only non-fiction should be accompanied by note-taking and diagram-scribbling that it never even occurred to them to do this. I realise that some people do much of their reading with one hand on a strap in a crowded bus or train carriage, but books simply don’t come with a guarantee that they can be properly enjoyed under such conditions.
maybe egan realized this is stupid because all of his subsequent physics-y books have online supplements written in textbook style, instead of the math being delivered in dialogue which, like, is just not a good way to read it.
As a result you get this "two-part" reading experience, with each part being suited to different contexts. I can read the online physics supplement at a cafe with a notebook open and a cup of coffee, and the story in bed. The only one I can claim to have fully understood is "Scale". In bed, it's a detective story, with the quirk that the woman who hires the private detective is about 8 times larger than him, and the suspects are about 8 times smaller than the detective. And the smaller people also think and age proportionally faster. At a cafe, it's a textbook-style exposition of the strange consequences of heavy leptons, and what it shows about the role of spatial scale and time in quantum mechanics.
I like it a lot, but it is, unfortunately, almost unique. Like other stuff has both technical and narrative components, but not so clearly separated in medium and style.
I can't think of one other example though, one of my favorite books ever: "To Explain the World", Stephen Weinberg's book on the history of physics from ancient Greece to Newton. It has a "technical appendix" with modernized versions of historical physics derivations. So, in bed, I read about how despite the sun and moon appearing the same size in the sky, there was one ancient Greek, Aristarchus, who figured out that the sun was much larger and farther away, and even proposed heliocentrism to place this extremely large body in the center. At a café, I can learn his argument.
This is astonishing because I think it's what I want from every book in some sense. I think when I read these wizard books there's some childish part of me that thinks I'm receiving incredibly important news, that people are capable of these spells, because maybe I will have an opportunity to learn the trick myself. With Weinberg's book, I actually do! Can't make history with it anymore but I can make the argument. Call it a divination spell, paying careful attention to the position of the moon and learning something from it. Really it's just solar-system scale surveying.
So it's wonderful and frustrating, because like I said, I really know of no other book like this. I mean there's Pais's history books, but like I said, that's not a two-part reading experience. It's annoying to try to follow the story while skipping the equations, and then go back to the equations later. I simulate it to some degree by reading pop science books and then separately reading the papers they mention, but it's hard--Weinberg is also modernizing the arguments. I would love to find something like a translation of Einstein's 1905 papers, with commentary including rephrasing in modern notation.
